User Interfaces; Button Definitions - Altair 5 Manuel D'utilisation

The ALTAIR 5 IR is available with a maximum of five sensors, which
can display readings for six separate gases (one Dual Toxic Sensor
provides both CO and H 2 S sensing capabilities in a single package).
The ALTAIR 5 and ALTAIR 5 IR Detectors are available with either a
monochrome or color display.
While the instrument can detect up to 25 % oxygen in ambient air, it is
approved for use only up to 21 % oxygen.
The alarm levels for the individual gases are factory-set but can be
changed through the instrument Setup Menu. These changes can also
be made through MSA Link

www.msanet.com. It is recommended that after making changes using
MSA Link, the unit should be turned OFF and ON.
